Occurrences
Numerical prefixes occur in 19th, 20th and 21st century coinages, mainly
the terms that are used in relation to or that are the names of
technological innovations, such as hexadecimal and bicycle.
They occur in constructed words such as systematic names. Systematic names
use numerical prefixes derived from Greek, with one principal exception,
nona-.
They occur as prefixes to units of measure in the SI system. See SI prefix.
They occur as prefixes to units of computer data. See binary prefixes.
They occur in words in the same languages as the original number word, and
their respective derivatives. (Strictly speaking, some of the common
citations of these occurrences are not in fact occurrences of the prefixes.
For example: millennium is not formed from milli-, but is in fact derived
from the same shared Latin root – mille.)
Because of the common inheritance of Greek and Latin roots across the
Romance languages, the import of much of that derived vocabulary into
non-Romance languages (such as into English via Norman French), and the
borrowing of 19th and 20th century coinages into many languages, the same
numerical prefixes occur in many languages.
Numerical prefixes are not restricted to denoting integers. Some of the SI
prefixes denote negative powers of 10, i.e. division by a multiple of 10
rather than multiplication by it. Several common-use numerical prefixes
denote vulgar fractions.
Words comprising non-technical numerical prefixes are usually not
hyphenated. This is not an absolute rule, however, and there are
exceptions. (For example: quarter-deck occurs in addition to quarterdeck.)
There are no exceptions for words comprising technical numerical prefixes,
though. Systematic names and words comprising SI prefixes and binary
prefixes are not hyphenated, by definition.
Nonetheless, for clarity, dictionaries list numerical prefixes in
hyphenated form, to distinguish the prefixes from words with the same
spellings (such as duo- and duo).
Several technical numerical prefixes are not derived from words for
numbers. (mega- is not derived from a number word, for example.) Similarly,
some are only derived from words for numbers inasmuch as they are word
play. (Peta- is word play on penta-, for example. See its etymology for
details.)
The root language of a numerical prefix need not be related to the root
language of the word that it prefixes. Some words comprising numerical
prefixes are hybrid words.
In certain classes of systematic names, there are a few other exceptions to
the rule of using Greek-derived numerical prefixes. The IUPAC nomenclature
of organic chemistry, for example, uses the numerical prefixes derived from
Greek, except for the prefix for 9 (as mentioned) and the prefixes from 1
to 4 (meth-, eth-, prop-, and but-), which are not derived from words for
numbers. These prefixes were invented by the IUPAC, deriving them from the
pre-existing names for several compounds that it was intended to preserve
in the new system: methane (via methyl which is in turn from the Greek word
for wine), ethane (from ethyl coined by Justus von Liebig in 1834), propane
(from propionic which is in turn from pro- and the Greek word for fat), and
butane (from butyl which is in turn from butyric which is in turn from the
Latin word for butter).
[edit] Table of non-technical numeric prefixes
This also includes the technical numeric prefixes used for systematic
names. For tables of other technical numeric prefixes, see SI prefixes and
binary prefixes.

[edit] Notes
^ Sometimes the prefixes are cited as though they were the original words
themselves. The prefixes derived from Greek are not only in the wrong
alphabet, but also differ from the corresponding Greek words. See the
individual word etymologies for the actual number words.
^ The prefixes in this column are also unbound morphemes.
^ See Mendeleev's predicted elements for the most common use of these
numerical prefixes.
^ Greek hexa-/hex- is sometimes used in words for 6, even when Latin
sexa-/sex- would be more etymologically appropriate, because of the
similarity to English “sex”[citation needed]; e.g. "hexadecimal".
^ The distinction between Latin and Greek is blurred in the case of 8.
Unlike the other numbers, there was little divergence between Latin and
Greek in the words for 8. Whilst octa- is primarily of Greek derivation,
octo- and oct- can be considered to be derived from both Greek and Latin.
^ Haplo-, from Greek haplóos "single"/"simple", is used only in genetics
to designate haploidy and related terms.
